摘要：
A method for forming a carbon supported catalyst includes a step of providing a first carbon supported catalyst having a platinum-group metal supported on a first carbon support. Characteristically, the first carbon support has a first average micropore diameter and a first average carbon surface area. The first carbon supported catalyst is contacted with an oxygen-containing gas at a temperature less than about 450° C. for a predetermined period of time to form a second carbon supported catalyst, wherein the first carbon support or the second carbon supported catalyst is acid leached.
